Standard Outdoor Temperature Sensor, included with all ULTIMETER Weather Stations.  A precision aged metal-oxide thermistor is used to measure temperature.  As the temperature increases, its electrical resistance decreases, changing a signal voltage that is first converted to digital form, then sent to the microprocessor.

WHY IS THIS OUTDOOR TEMPERATURE SENSOR BETTER?

• Each sensor is precision calibrated for complete interchangeability.
• Each sensor is specially aged to assure long term stability.
• The microprocessor is programmed to make minute corrections over the specified temperature range, further enhancing the resultant accuracy.
• No user calibration is required or provided for, because of the precision interchangeability of the sensor elements, even in the event of sensor replacement.       

Includes 25 ft. 4-conductor cable (longer cable lengths optional).
